Draping a drain arc over a TIN

Assuming you already have the TIN of the drain bottom elevation you need - Create the ark for the drain, select the nodes, right click on a node and select "attribute table" at the right hand side of the yellow box at the top of the bot.elv. list, click on the arrow head and select "TIN" then select the required tin of the bottom elevation from the list. As the elevation is only assigned to the nodes on the arc, and not the vertices, if your topography is variable, subdivide the arc in to a lot of vertices (there is no point in going closer spacing than the grid spacing), convert the vertices to nodes, then go though the process again.
